The rules for the documentary series are simple. Each film has to examine sports history in some way, and the filmmaker has to be passionate about the project. The idea for the series first came from Grantland founder Bill Simmons in 2007, when it was originally conceived as creating 30 sports history films for ESPN’s 30th birthday — hence the series’ name. Since then, dozens of documentaries have been created, and a lot of them are excellent. From Broke’s exploration of misguided wealth in the NFL to Fantastic Lies’ disturbing and unexpected look into the Duke lacrosse scandal, ESPN’s 30 for 30 series offers a rare behind-the-scenes look into sports culture explained in a way that both sports fans and sports haters can appreciate. By our count, Netflix used to have 69 of these documentaries. Now they’re all gone from the service.

People on social media have certainly noticed the departure of these documentaries. As recently as this week, you can find tweets from fans lamenting the expiration of these titles. Responses have ranged from defeated to intensely angry, and, as is always the case when a big title leaves Netflix, there have been threats from subscribers to cancel their account.

A Reddit thread lamenting the departure of these titles has also gained a fair amount of attention in r/netflix. As the original post points out, the departure of this content is a big blow for Netflix’s lineup of documentaries, which largely focus on nature and lifestyle-type docs. Because Netflix doesn’t have a live programming option, there are few sports-focused titles on the service. ESPN’s series did a lot to help fill that gap. The 30 for 30 series was never a selling point for Netflix, but it was a delightful streaming surprise and one of those hidden gems that made Netflix worth the investment.

Currently, there are no public plans to bring the series back to Netflix. When asked to comment about the 30 for 30’s expiration from Netflix, a representative for ESPN had this to say: “Consumers can access ESPN original content via Watch ESPN and ESPN Video On Demand, as well as Hulu, iTunes, Amazon Instant Video and Google Play.”

Decider also reached out to Netflix for a comment about 30 for 30‘s expiration. In their response, a spokesperson for the streaming service explained the many factors that are at play when it comes to deciding whether or not Netflix should renew a title:

“The license for a TV series or movie is for a set period of time, which means every title eventually comes up for renewal. To determine renewal, we take a variety of factors into account including how much the title is being viewed, member rating feedback and the amount of similar titles already available, among other considerations to determine how much we’re willing to pay to potentially renew a title. There are also times when its not up to Netflix to renew, i.e. when a a licensing period ends and a show or movies goes to another TV channel or service or when we work with studio partners on a rotating section of content. In the case we do not or cannot renew, we put the money toward other content we think our members will enjoy.”

Of course, there’s always a chance that the 30 for 30 series may come back to Netflix. It’s not uncommon for titles to leave the service for a couple of months while the studio and Netflix renegotiate the terms of their contract. Considering that Netflix has an exclusive deal with Disney, which owns ESPN, Netflix likely has a leg up on re-acquiring the rights to the documentary series over competing streaming services like Hulu or Prime Video. Still, the loss of 30 for 30 hurts. Without 30 for 30, how will we know who killed the USFL? (Donald Trump) Or why Christian Laettner is so despised? Hopefully these documentaries will return to Netflix soon.
